Tigre debuted in Primera División, the top division of Argentine football, on 1 May 1913 against Porteño; the match concluded in a 0–0 draw.

The team played its home matches on a field located on Rocha street, near Reconquista River in Rincón de Milberg.

When a new schism came in 1919, Tigre registered to dissident Asociación Amateurs de Football, which lasted until 1927, when both leagues, AAmF and AFA joined.

In October 1944, the club received then vice-president of Argentina, colonel Juan Domingo Perón, in front of a crowded stadium.

The club finished with a total of 39 points, tied for first place along with San Lorenzo and Boca Juniors, but ends as runner-up after playing a historic triangular final.

Tigre started the season thinking about not being in the relegation table, but ended up exceeding the expectations by fighting for the league title until the last date.
